Exhaust Manifold Gasket Job.

Couple days ago I brought a truck in for an inspection and noticed there was a lot of black dust behind the exhaust manifold. I further inspected it and found that the gaskets on this Mercedes engine were most likely bad. So I ordered all of the parts from freightliner and luckily they had them in stock so by the time I pulled everything apart the parts showed up. Again i was alone at the shop working late so i had to think of everything on my own. The first problem I ran into was the turbo nuts where extremely tight. Two of the nuts came out when I put a three foot pipe on the end of my ratchet. But the other two at this point were pretty rounded off. I tried heating the nut up and it didn't work, So then I heated up the base of the turbo and exhaust manifold where they meet so that I could just try to remove it and the stud would just come out instead of the bolt coming loose. And this worked out well and I ended up replacing the studs. In two weeks I did two exhaust manifold jobs. The first job four bolts from the exhaust manifold broke which then I had to use an alignment block and reverse drill bits to extract the broken bolts. So this time I was very careful and I heated up the bolts before taking them off as best that i could to break the rust. It worked out well none of the bolts broke. The rest of the job went good I changed out the gaskets and fired up the truck took it for a test drive and there were no problems. Here are some pictures...

This how I realigned all the bolts and got the exhaust manifold mounted.

Today I went through a series of courses on basic electrical. It was a nice review and I got to brush up on some things that I was not sure about. I went through all six of the courses and got a 97%. Here is a screenshot of the completion and I will be getting a certificate in the mail.

Gear box

Couple days ago I brought a truck in for an inspection and I found that the gear box was leaking from the main shaft. So we had one in stock and I changed it out. Pretty easy job only hard part is that the box is pretty heavy and aligning the bolts up took a couple tries. Also I used the box end of the 1 5/16 wrench and put it again the top part of the frame rail so that I could take the nut off with the impact gun. I usually work alone because while going to school I have to work late by my self so I find ways to help my self out. Here are some pictures....
